A coordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom. A covalent bond is formed by two atoms sharing a pair of electrons. The atoms are held together because the electron pair is attracted by both of the nuclei.
Share. Covalent Bond Definition: A covalent bond is a chemical link between two atoms in which electrons are shared between them. Examples: There is a covalent bond between the oxygen and each hydrogen in a water molecule (H 2 O).Each of the covalent bonds contains two electrons-one from a hydrogen atom and one from the oxygen atom.
